Good To Know

Q: Will this converter charge my RV battery as well as run 12V lights? A: Yes, a 55 amp converter supplies enough current to run 12V loads and charge the house battery at the same time. Heavier loads like a jack or slide motor may draw more than the converter alone provides.

Q: Is this a direct swap for a Parallax 7145? A: It is built as a replacement for the 7145, 7155, WF-8955, and WF-8900 series, so the wiring layout matches on most installs. Always verify your existing breaker and fuse panel connections before wiring it in.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
